Rolex Daytona User Instructions: Under normal circumstances, the pushers at the 2‑o’clock and 4‑o’clock positions are locked. This thoughtful design helps prevent accidental operation.

When the crown is unlocked, the chronograph seconds hand remains stationary until you press the chronograph pusher; it does not run continuously like a regular seconds hand.
Chronograph minutes hand: it advances one small increment each time the chronograph seconds hand completes one full rotation.
The running seconds hand moves continuously in daily use.
No further explanation is needed for the chronograph hours hand.

Rotate the pushers at the 2‑o’clock and 4‑o’clock positions counter‑clockwise to unlock them.
Press the 2‑o’clock pusher to start the chronograph. Press it a second time to pause timing.
Press the 4‑o’clock pusher to reset all hands back to zero.
You must follow this correct operating sequence. Do not press the 4‑o’clock reset pusher while the chronograph is still running without first stopping it.

Avoid frequent use of the chronograph function in daily wear, as it consumes power reserve. Always follow the proper operating sequence: start the chronograph, pause it, then perform the reset. Never press the reset pusher while the chronograph is running.
